Patent DE-3107630-A1 (DE)
Title: Method and circuit arrangement for duplex data transmission via a two-wire line
Inventor: SCHENK HEINRICH DR ING
IPC: H04L5/06
Filed: 1981-02-27
Abstract: Method for duplex data transmission via a two-wire line (L). In quadrature modulation, a modulated upper or lower data signal (A or a) is in each case generated with the aid of an upper or lower carrier frequency (F or f) for each transmission direction, transmitted and demodulated. The upper carrier frequency (F) is equal to double the lower carrier frequency (f) and an integral multiple of a modulation segment (T). The upper or lower data signal (A or a) is sampled with a multiple of the upper carrier frequency (F) and corresponding upper or lower data words are obtained. When the upper data signal (A) is received, lower data words are fed at intervals of 1/4F to digital low-pass filters (TP1, TP2). The lower data words are fed at intervals of 1/2F to further low-pass filters. The data emitted by the low-pass filters are forwarded once per modulation segment to corresponding decision stages. <IMAGE>

Patent DE-3118623-A1 (DE)
Title: Circuit arrangement for forming the square of the number of pulses of a pulse sequence received in a pulse counter
Inventor: STEINMUELLER GUENTER ING GRAD
IPC: G06F7/62
Filed: 1981-05-11
Abstract: The invention relates to a circuit arrangement (A) for forming the square of the number of pulses of a pulse sequence received in a pulse counter (1) in a memory (8). Previously used circuit arrangements for squaring a pulse number contain digital multipliers of complicated configuration. By comparison, the circuit arrangement according to the invention is based on the fact that any square number can be represented as the sum of the successive odd numbers in accordance with the relation <IMAGE> (2m + 1). For this purpose, the pulse sequence (I) is conducted to the transfer clock input (T) of a k-stage down-counter (3) with binary set inputs (P1 to Pk) and via a delay section (4) to the counting input (Z) of an up-counter, used as pulse counter (1) having at least k-1 binary outputs (Q1-Q(k-1)) and with a reset input (R). The output pulses of a pulse generator (6), the frequency of which is much higher than the maximum frequency of the pulse sequence (I), is present at the counting-down input (RZ) of the down-counter (3) whenever, and only when, the input of the down-counter (3) is greater than zero. The pulses present at the counting-down input (RZ) of the down-counter (3) are supplied to a resettable accumulating counting mechanism (8). A set signal is always applied to the binary set input (P1) of least significance and the binary set inputs (P2 to Pk) of higher significance are in each case connected to one of the binary outputs (Q1 to Q(k-1)) of the up-counter (1) in accordance with rising significance. <IMAGE>
Patent DE-3126055-A1 (DE)
Title: Battery charging system
Inventor: GANSERT WILLI ING GRAD
IPC: H02J7/00
Filed: 1981-07-02
Abstract: A battery charging system is proposed which has an AC generator (10), a voltage regulator (20) and a charge monitoring device for indicating defects. The latter is provided with a signal transmitter (82) for detecting the switching state of the voltage regulator, a first threshold-value stage (67) for detecting a minimum value of the generator voltage, and a second threshold-value stage (69) for detecting a voltage which is a specific amount above the required control value, at a sensing point in the system. One input of the first threshold-value stage (67) is connected to a fault detection connection (D+), which is decoupled from the battery voltage, on the excitation system (12, 14) of the generator. The second threshold-value stage (69) is connected on the input side to a sensing point which is influenced by the battery voltage. This has the advantage that the first threshold-value stage (67) can detect and evaluate the generator voltage without being influenced by the charge state of the battery and without being corrupted, and the second threshold-value stage can detect and evaluate the charge state of the battery without being corrupted. <IMAGE>
Patent DE-3129710-A1 (DE)
Title: Ratchet spanner
Inventor: GRZANNA KURT
IPC: B25B13/46
Filed: 1981-07-22
Abstract: In order to be able to use a ratchet spanner even if a part (e.g. a nut) has to be turned which is inaccessible to a ring spanner, the chuck (42) of a ratchet spanner as well as its head (41) are designed according to the invention in a jaw shape. If such a ratchet spanner can no longer be removed radially after the part (nut) is turned, it can be pulled axially off the part in order to first of all disengage it from this part. The chuck (42) in the head (41) can then be turned to such an extent (see Figure 2) that the ratchet spanner can be removed radially from the component (e.g. a tube) preventing the use of a ring spanner. <IMAGE>

Patent DE-3138043-A1 (DE)
Title: Section monitoring device
Inventor: KRUG ADOLF DR ING
IPC: B61L25/04
Filed: 1981-09-24
Abstract: On a track-guided vehicle (F), a response device (A) is provided which, in accordance with an associated item of information, transfers a response signal to an interrogating device (AB). The interrogating device (AB) is in each case associated with two antenna devices (A1, A2), the zones of action of which are aligned in such a manner that when the response device (A) passes, the latter first enters the zone of action of the first antenna device (A1), then an area of overlap of the zones of action of the two antenna devices (A1, A2) and lastly passes through the zone of action of the second antenna device (A2). The two antenna devices (A1, A2) in each case address one of two planes of polarisation which are perpendicular to one another. From the response device (A), the response signal is sent out in these two planes of polarisation. The overlapping influence on the antenna devices (A1, A2) supplies a criterion on the direction of the passage of a vehicle (F) with respect to the site of the interrogating device (AB) and thus also information on the state of occupancy of the two adjoining track sections (I, II). <IMAGE>

The control shaft interacts with locking levers (6), movable in a reciprocating manner between an operative and an inoperative position, for locking and releasing the tools, each of which is to be allocated in each case to one of the operations of the respective work program. When the control shaft (2) is rotated about its axis, the locking levers (6) enable the tools to be inserted one after the other into the allocated tool holder of the housing or they release the tools for removal. <IMAGE>
Patent DE-3140369-A1 (DE)
Title: Air outlet for room ventilation
Inventor: ADAM JAKOB
IPC: F24F13/075
Filed: 1981-10-10
Abstract: The outlet has fixed slats (2) and movable slats (6). The movable slats (6) can by their gravitational force (R) move in the direction of a closed position, in which they increasingly narrow the intermediate spaces (9) which exist with the slats (6) raised. The fixed slats (2) can be pivoted by means of a servomotor (5) and a linkage (4). By means of the invention, it is brought about that the outlet cross-section (9) is automatically reduced with decreasing air quantity, without complicated regulating devices being necessary for this. As a result, even with a relatively low conveyed quantity, a relatively high air speed is maintained and thus good flushing through of the room is guaranteed. <IMAGE>
Patent DE-3146843-A1 (DE)
Title: Gas-powered, water-cooled internal combustion engine
Inventor: BERGMANN HORST
IPC: F02M1/16
Filed: 1981-11-26
Abstract: The invention relates to a water-cooled internal combustion engine powered by gaseous fuel. The gas - alcohol - is stored in the liquid state in a fuel tank. In order to overcome the difficulties when starting at low ambient temperatures, in particular in order to shorten the initial production of gas, a heating device is provided for vaporising the fuel which directly vaporises the fuel and thereby permits rapid starting. In the heating device fuel is burnt in a small burner in a known manner. The combustion heat released heats a fuel line and quickly vaporises the fuel flowing through it. The fuel vapour thereby produced is fed directly to the intake pipe of the internal combustion engine or to the vapour chamber of the fuel vaporiser. The heating device produces more fuel vapour than is required for idling of the cold internal combustion engine so that it is also possible to run up to partial load and for a short time up to full load. As soon as a separate, exhaust gas-heated water circuit and/or the cooling water circuit of the internal combustion engine has reached the vaporisation temperature of the fuel, the heating device is automatically switched off.

Title: Electronic device for detecting operating data of a motor vehicle
Inventor: WESSER DIETER
IPC: G07C5/08
Filed: 1981-11-28
Abstract: An electronic device (1) for detecting operating data of a motor vehicle with apparatuses for characterising the start and the end of a journey and with apparatuses for detecting the distance covered during a journey, is characterised in that the electronic device for characterising the start of a journey has an apparatus which responds to the rise in the electric voltage at an externally presented terminal of the device, in that, for the purpose of collecting the data required for a journey log, it has a keyboard (15) for inputting alphanumeric information and a multiplicity of control keys (4 to 11, 14), at least for characterising the type of journey or the respective driver, in order to input the route and in order to characterise an interruption in the journey, in that at least some of the control keys (4 to 11) are assigned a controllable LED (LEDs 18, 19), in that it has an electronic working memory, an apparatus for outputting data stored in the working memory and a control apparatus which is constructed in such a way and controls the device in such a way that, when a voltage is applied to the terminal responding to the voltage rise, the LEDs light up in the sequence of the control keys to be pressed by the user and of the information to be input, data contained in the working memory being retained when the journey interruption key (5) is pressed. As a result, the continuous collection of data required for a journey log is made easier. <IMAGE>
Patent DE-3149987-A1 (DE)
Title: Burner device
Inventor: SIEVERT ERNST-JOACHIM
IPC: F23M5/02
Filed: 1981-12-17
Abstract: In burner devices for the alternate firing of glass melting furnaces according to the Siemens-Martin principle, there is the disadvantage that additional air is sucked into the furnace space by the injector effect of the burner which is already in operation. The other burner, which is not in operation, is usually cooled with compressed air and, consequently, additional air will also enter the furnace space at this point. As a result, there is overall a poor energy balance. To eliminate these disadvantages, the burner lance is, in the burner device according to the invention, arranged displaceably, and the furnace space is, moreover, closable at the point where the burners are situated. The burner which is not in operation can thus be moved outwards and the opening to the furnace space can be closed. As a result, no additional air enters the furnace space at this point and, conversely, no heat can radiate outwards from the furnace space.

Title: Method of welding a workpiece by means of a focussed electron beam
Inventor: NOLLER FRIEDEMANN DR ING
IPC: B23K15/00
Filed: 1982-11-05
Abstract: In a method of welding a workpiece (10) by means of a focussed electron beam, the point of impact of the electron beam is displaced relative to the workpiece or the workpiece is displaced relative to the point of impact on a predetermined path curve (12). In addition, the point of impact is diverted to a modulation curve relative to the path curve. The electron beam impinging on the workpiece transmits its energy in the form of heat to the workpiece and heats it locally above the melting and vaporising temperature. This results in a melting zone (14) as well as a vapour capillary (20) arranged inside the melting zone (14) in the direct impact area of the electron beam. On account of the movement of the workpiece relative to the point of impact, a flow (30) is produced inside the melting zone (14), which flow (30) is passed from the front side (24) (as viewed in the opposite direction to the direction of movement of the workpiece) around the vapour capillary (20) to the rear side (26). In order to obtain good welding results free of root voids and spatter at the top and bottom bead, the oscillating movement of the electron beam on the modulation curve is adapted to the flow conditions in the melting zone. <IMAGE>
